Picking up 2 IDMAX-10 v3 D4 subs today and wondering if the JL 1000/1 would be enough to push em. In the past I had 2 JL 10 w7's powered by a JL 1000/1 and it pounded fine. Unfortunately those were stolen. Right now I currently have a JL 500/1 to my 10w6v2. Going to sell the 500/1. Thanks!

sealed? somewhat
ported? yes
IB? yes

sealed in 4080 boxes.

The 4080 enclosures are obviously a compromise favoring space-saving over internal volume. Using an IDMAX will require slight modification to the enclosure to accommodate the driver depth (for the driver's-side). I'm not familiar with the depth of the passenger-side enclosure. I ran a single IDMAX10 in a 4080 enclosure from a pair of bridged channels of a Zapco Reference amp at approximately 500WRMS. It performed well. The 4080 is a well-built piece. If you need to save space, it's a good choice.

Thanks for the reply Kurtis. I am now trying to find the mounting depth of the 4080 passenger coupe box. From what i remember, it was slightly shorter than the drivers side. Now that the 4080enclosure website is no longer up, Im having a hard time finding the exact specs. And the new boxology website is not showing the specs.

Those subs may not fit

If they don't, IB would be a good route to go

I looked back at my F/S thread and found a couple of pics and the recommended sealed volume for the IDMAX10. Recommended is 0.6-0.9 cu. ft. I don't recall the volume of the 4080 but it was less than 1.0 cu. ft. Using a 1.5" mdf spacer ring will increase your internal volume slightly (0.06 cu. ft.) You'll have to come up with your own solution for a grille since the 4080 grille won't fit with this sub.

I believe it's roughly about .78 cu. ft. per box. Kurtis, your pictures are actually what I found when doing a search recently and what made decide to try this route.

The IDMax 10 will only physically fit if it is surface mounted like the above pics. (nice mod, by the way!)

The standard enclosure airspace is .78 but when you surface mount a sub you gain some airspace. I have built a few for surface mounted 12's by cutting out the recessed mounting structure and glassin' a ring on the front. The available airspace was increased to .9 cu. ft. before driver displacement on those one-off coupe enclosures.

The other thing to consider is that the driver mounting diameter for the IDMax 10 is larger than normal... 9.6 inches just like the IDQ. The IDQ just required a different mounting ring to be inserted in the molds as they physically fit in both sides but the IDMax 10 will not physically fit with the standard mounting system so the only option is to move it forward for clearance.

Thanks for the reply BOXOLOGY. Do you happen to know the standard mounting depth of the classic 4080 coupe box both drivers and passengers side? That would determine the size spacer to add to the current box. Thanks!

7" deep with 6" wide tapered magnet, the passenger side needs to be notched to accomodate this size (where the cut-in for the cargo-net hook is).

HOWEVER!!! The reason depth is not listed is because it is a case by case basis because the location of the terminals on the subs and side profile will make or break the actual fit!

As an authorized ID dealer (well, until Eric and Matt left that is now it is up in the air if we will continue with ID) I can tell you that the IDMax 10 needs to be surface mounted or they can be flush mounted with a double-stacked countersinking ring. That is not only to accomodate the depth and profile of the sub but also recommended to get the best out of them as those specific subs perform better with the added airspace.

The other options are to ditch your spare, build a false floor, and run vented or sealed or just go Infinite baffle with them. With IB on the G35 coupe, you have some major work to do to totally seal the trunk from the cabin and will add the same if not more overall weight as an enclosure(s) if you do it properly. You also have to factor in the loss of trunk space where the magnets will sit along with losing the rear seat pass-through option.

Are you modifying some old boxes?

I was planning to do what k67p67 did and add 1.5 mdf spacer rings to each box to accomodate the depth of the idmax. Thanks for your help and feedback BOXOLOGY!

You bet. Have fun with it and you might be able to get away with just using one spacer ring, not sure but give it a shot if you'd like.

As a side note, k67p67 that is one old 4080 and it seems to be holding up quite well... I made that one way back when I wasn't powder-coating the brackets!

1000/1 is a beast ive seen that monstor power 2 12w7s in a HObox very underrated amp.

There's nothing beast or underrated about it
